Again, a 'stop' at a sensible limit with a 'conscious' over-ride option for when the horses in the hold break loose would do it, would it not?
Maybe, but a sensible limit would be "configuration conscious". 2 or 3 ANU might be fine for cruise, but full flap, extreme fwd CG and Vref with a modest allowance for a steady turn might need 12 deg or so.
Possibly one simple solution might be to have THS deflections limited according to the slat/flap selection (with no over-ride - anything beyond that limit would have to be held by elevator deflection)
